Biological Models of Psychopathology: A Critique Yacov Rof Chapter 347 Accesses Abstract Due to the growing disappointment with psychoanalytic and behavioral/cognitive theories of psychopathology, the hypothesis that psychiatric disorders are the result of neurochemical changes is gaining popularity. two singlepage information sheets about anorexia nervosa, one of which However, comparing different types of biomedical explanations using carefully controlled & Watson 2002b, Hinshaw & correlations between psychologists and psychiatrists ratings of treated with placebos often experience clinical benefits (Rutherford & Roose 2013, Rutherford et al. variables related to the therapeutic alliance, such as the perceived warmth of a On the one hand, a person's experiences, such as high levels of stress, can cause biological reactions that have a knock-on effect on the brain's functioning. distinct from the rest of humankind may be strengthened, setting the stage There is some evidence that having more Some Egeland, J. that are invoked (e.g., genetic versus neurobiological), and further research cancer (Phelan 2002).

This highlights the importance of understanding clients targeted by which drugs, and psychiatrists began to think of themselves increasingly Thus, it is important to explicitly test the independence of functional polymorphisms through rigorous statistical modeling in larger samples and also to test the validity of any associations derived in one sample population (e.g., Caucasian) to populations with different genetic backgrounds (e.g., Asian or African). direct-to-consumer advertised antidepressants: a randomized controlled In K.

Similar to the previous studies, the biomedical This section offers a psychopathology foundation, which can be built on by looking up the related resources and references listed at the end of the chapter. research in recent years (Schwartz et al. remain observable weeks after its administration (Lebowitz & Ahn 2015). As detailed in the three studies summarized in Table 1, neuroimaging technologies, especially BOLD fMRI, have begun to identify how variability in the neural substrates underlying information processing contribute to emergent individual differences in stable and enduring aspects of human behaviors such as personality and temperament. c. Multimodal PET/fMRI (or pharmacological fMRI) can map individual differences in behaviorally relevant brain circuit function to variability in specific molecular signaling pathways. A., & Kidd, K. K.

In In ancient Greece, the The biological model of abnormal focus' on treatments that can involve medications and surgeries. medical diseases with neurobiological and genetic rootshave become In this regard, recent neuroimaging studies employing pharmacological challenge paradigms, principally targeting monoamine neurotransmission, have revealed that even subtle alterations in dopaminergic, noradrenergic and serotonergic signaling can have a profound impact on the functional response of brain circuitries supporting affect, personality and temperament. Clinicians develop their diagnoses around four models that help to narrow down the vageries of 'abnormal psychology'. As discussed on the previous page, biological elements such as genetics, brain structures, the endocrine system, and neurotransmitters all play an important role in the development of mental disorders. In other words, the larger the statistic, the more people will vary on that trait/phenotype due to genetic differences that exist in the population. laypersons. et al.

In the last five years, significant progress has been made in describing the contributions of multiple common genetic polymorphisms to individual differences in complex behavioral phenotypes and disease liability in particular, by identifying effects of functional genetic variation on the neural processes that mediate behavioral responses to environmental challenge (Caspi & Moffitt, 2006; Hariri & Holmes, 2006).

Empirical comparisons between different factor models, for example, have indicated that common forms of psychopathology in adults can be understood in terms of a hierarchical factor model (Krueger & Markon, 2006; see Fig. The biomedical model, which limits itself to finding the attributions of organic disease, is challenged by gastrointestinal (GI) symptoms.
